I've been successfully dragging one item at a time over from a listbox to a treeview, but now that I'm trying to adapt it to drag/drop multiple items, I've run into a problem.I'm getting an index out of range exception in the loop where I'm trying to gather the listbox items into a string array. Any index greater than 0 throws the exception, even though I have set the length to equal the number of selected items in the listbox. I've double-checked that this is the case many times. Watching the selecteditems.count value, I can see that it is equal to the number of items I have selected, naturally, but the exception is still thrown on this line:
sel(i) = AddonsList.SelectedItems.Item(i)
Here is the relevant drag/drop

I have a simple textfile which I want to drag-drop into the treeview. After the drop read the textfile (line by line) and create the nodes. There are no subnodes (what-so-ever). File looks like this:

I am building a 'shape editor' which looks very similar to the Visual Studio form designer. I have a Toolbox control that holds a few 'Shapes' (such as RectangleShape, EllipseShape, TriangleShape, etc) which the user should be able to drag to the design view ("Canvas") in any MDI form. The Toolbox control is just a TreeView except that I add ToolboxItems to it (which are inherited TreeNodes). This dragging however does not seem to work...

drag and drop nodes within the same tree (not between trees) when users drag and drop nodes within the tree, give them the option to move the original node to a new location within the tree OR to just copy the original node in a new location (seems complex but I have a month to figure this out). change the system default blue highlight for selected nodes to another color change the system default cursors for invalid and valid drops (instead of the circle with slash indicating invalid target, i want a red minus) and (instead of the little plus sign with little box indicating a valid target, i want just a big green plus sign) add a red insert line to indicate where the node would be dropped within a tree also drag and drop the text of a node from the tree to a textbox add a "folder" image next to parent nodes and a "document" image next to children nodes

I want to be able to hold CTRL down to select multiple text entries and drag them all to certain text boxes. Or even one at a time, but once I try dragging another word into the box it replace the first one. Is there any way to just have it add to the text box rather than replace it?
And if possible, place a "-" between each entry?

View 4 RepliesI am writing a small program that has two list box's which are populated from my sql database. I want to drag an item from LB1 to column1 in a datagridview and drag an item from LB2 to column2 in the same datagridview.
I am getting close, but I am having trouble getting the data to drop. I did some testing and I can drop a string, but I am not able to get the string data from my listbox. I just get a datarowview. I see the string inside the "itemarray", but cannot get to it.

I've seen the code on this site to setup a drag-and-drop between 2 listboxes (and that works perfectly for me), but I have a need to be able to move items between up to 12 listboxes. For example, I move an item from listbox1 to listbox2; at some point in the future, I need to be able to move that same item from listbox2 to listbox3, then at another point in time from listbox3 back to listbox1, etc. When I make these moves, I need the item to be removed from its previous location. I've attempted to modify the 2-listbox code to include, on my test form, a third listbox, but that code copies to the third listbox, and when I attempt to move the item from the third listbox to the second, it, too, only copies and does not remove the item from listbox3.
